SPECIFICATION forming' part of Letters Patent No. 718,737, dated January20, 1903. Application filed June 2,1902. Serial No. 109,950. (No model):

To ttZZ whom, it may concern:

Be it known that I, HILLYARD A. STARR, a citizen of the United States,residing atEast Chattanooga, in the county of Hamilton and StateofTennessee, have invented certain new and useful Improvements in Meansfor Fastening Shades to Shade-Rollers; and I do declare the following tobe a full, clear, and exact description of theinventiomsuch as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to means for fastening window-shades toshade-rollers.

The object of the invention is to provide simple and effective means ofthis character by means of which the shade will be securely held inposition without the use of tacks and whereby liability of the shadepulling or tearing away from its fastening will be avoided.

With the above and other objects in view, which will readily appear asthe nature of the invention is better understood, said inventionconsists in certain novel features of construction and combination andarrangement of parts, which will be hereinafter fully described andclaimed, and illustrated in the accompanying drawings, in which Figure 1is a front elevation of a shaderoller embodying my invent-ion. Fig. 2 isan end elevation thereof, showing the shade drawn down to its fullestextent and also showing a portion of the roller broken away to exposethe clasp. Fig. 3 is a perspective view of the clasp. Fig. a is asimilar view of a different form of clasp.

Referring now more particularly to the drawings, the numeral 1represents a spring shade-roller of ordinary form except as hereinafterdescribed, the same being provided with the washer or cap 2 at one ofits ends and the ferrule 3 at its opposite end, said ferrule formingpart of the support for the dog-andratchet mechanism in the usualmanner.

4. represents the shaft of the roller, which extends at one end throughthe ferrule 3 and coacts with the ordinary form of spring. (Not shown.)

In carrying my invention into practice I provide the roller with alongitudinal groove 5, which coincides with an opening 6 in the head 2and extends beneath the ferrule 3. This groove is adapted to receive andretain a rod or wire 8, headed at one end and adapted to be passedthrough the opening 6 and thence beneath the ferrule 3, said head andferrule thus acting as end supports to hold the rod in position. Theupper end of the window-shade 7 is passed one or more times around therod, which is then seated in the groove, and holds the end of the shadepressed firmly against the roller. To render the fastening absolutelysecure, I provide a clasp to reinforce the action of the rod and to bearupon the shade. This clasp in the form shown in Figs. 1, 2, and 3consists of a U- shaped plate of spring metal, which is bent or coiledinto nearly'circular form and closely encompasses the roller, the saidclasp being provided at its free ends with spurs or teeth 10 topenetrate the roller and hold said clasp in position. 'As shown in Fig.2, the shade 7 passes from the rod 8 in one direction nearly around theroller and is engaged by the clasp 9, the free ends of which cross overthe rod and act as supplemental fastenings to retain the same in place,while the spurs 10 are forced into the roller and serve to hold theclasp against longitudinal and axial play. It will thus be seen that asthe rod 8 retains the ends of the shade in the groove and the clasp 0retains that portion of the shade which is passed around the rollersecurely in place all liability of the shade becoming disconnected fromthe roller under any ordinary pull or strain will be entirely avoided.Of course it will be understood that any desired number of clasps may beemployed and that where but one is used it is preferably located at ornear the center of the roller in order to reinforce the action of therod at a central point.

While the U or double form of clasp shown in Figs. 1, 2, and 3 is deemedpreferable, in some cases the single or ring-shaped form of clasp shownin Fig. 4 may be employed and will render effective service.

By mounting the shade upon the rolls in the manner described when theshade is drawn downward to its fullest extent the dogs will be out ofengagement with the rack, as shown in Fig. 2, thereby preventing theroller from being caught at this point and leaving the shade free tomove up at the will of the operator. By this means the necessity ofresetting the roll, which occurs when the shade is caught in theordinary construction, is entirely avoided.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought that the construction, mode ofoperation, and advantages of my improved means for fastening shades toshade-rollers will be readily apparent without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with ash-ade-rollerprovided with a longitudinalgroove and a retaining rod adapted to seat therein; of aclasp embracingthe roller and bearing upon the rod and provided with spurs entering theroller, substantially as described.

2. A shade-roller provided with a head and a ferrule at its oppositeends and having a longitudinal groove extending beneath the ferrule andcoinciding with an opening in the head, and a retainingrod adapted to bepassed through the opening in the head and beneath the ferrule and toseat Within said groove and insertible and withdrawable longitudinallythrough the groove and head, substantially as specified.

3. The combination with ashade-roller provided with a longitudinalgroove; of a shaderetaining rod seated in said groove, means for holdingthe rod in position, and a clasp adapted to embrace the roller and tobear against a portion of the shade passing therearound and tosupplement the holding action of the rod, said clasp also bearingagainst the rod and supplementing the action of said holding means,substantially as set forth.

4. The combination with ashade-roller provided with a longitudinalgroove; of a rod adapted to seat therein, and a clasp comprising aU-shaped piece of spring metal bent into nearly circular form tosurround the roller and provided with spurs at its free ends,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
